Remember that penis transplant surgery conducted on a South African man several months ago? Turns out it was a major success.

The 21-year-old man, who hasn’t been identified for privacy reasons, has impregnated his girlfriend. Yes, that’s right. Mere months after receiving his new…um…appendage, he’s already firing on all cylinders. His girlfriend is reportedly four months pregnant.

After losing his penis three years ago following complications arising from a circumcision procedure, the man underwent the transplant in December. Dr. Andre van der Merwe from Stellenbosch University in Cape Town, along with a team of fellow surgeons, performed the nine-hour surgery to transplant a “good normal penis” (Van der Merwe’s words) harvested from an organ donor.

“This is what we intended, that he should be able to stand up and be able to urinate and have intercourse,” Van der Merwe said. “So it is a milestone for him.”

“I know that he can ejaculate normally and there is no reason for him to be infertile. I was expecting a pregnancy at some stage, even though I didn’t expect it this early,” he said.

The patient is the second known person to undergo a penis transplant. The first one, who underwent the procedure in China, suffered a severe psychological reaction and asked to have the organ removed.

South Africa has a greater need for penis transplants than most of the world, due to many young men being members of the Xhosa people, who often undergo ritual circumcision, sometimes in rural areas without proper medical tools or sterilization. Van der Merwe’s pioneering surgery can now provide hope to the unfortunate young men.

Van der Merwe’s team said the procedure could eventually be offered to men who’ve lost their penises to cancer, or as a last resort for severe erectile dysfunction. The doctor has already received requests for the surgery from as far away as Colombia, Russia and the United States.
